Check Router Quota and ns Quota:

$ hdfs dfsrouteradmin -ls /ns10t
Mount Table Entries:
Source Destinations Owner
Group Mode Quota/Usage
/ns10t ns10->/ns10t hadp
hadp rwxr-xr-x [NsQuota: 150/319, SsQuota:
-/-]
/ns10t/ns1mountpoint ns1->/a/tt hadp
hadp rwxr-xr-x [NsQuota: -/-, SsQuota: -/-]
$ hdfs dfs -count -q hdfs://ns10/ns10t
150 -155 none inf 3
302 0 hdfs://ns10/ns10t
{code}
Update Router Quota:
{code:java}
$ hdfs dfsrouteradmin -setQuota /ns10t -nsQuota 400
Successfully set quota for mount point /ns10t
{code}
Check Router Quota and ns Quota:
{code:java}
$ hdfs dfsrouteradmin -ls /ns10t
Mount Table Entries:
Source Destinations Owner
Group Mode Quota/Usage
/ns10t ns10->/ns10t hadp
hadp rwxr-xr-x [NsQuota: 400/319, SsQuota:
-/-]
/ns10t/ns1mountpoint ns1->/a/tt hadp
hadp rwxr-xr-x [NsQuota: -/-, SsQuota: -/-]
$ hdfs dfs -count -q hdfs://ns10/ns10t
